[0023] Example 1:

[0024] like Figures 1-4 As shown, this embodiment provides a rubber sheath expansion assembly tooling, including: a mounting plate 1 and a fixing component disposed on the upper surface of the mounting plate 1, wherein the lower surface of the mounting plate 1 is provided with a plurality of support columns 12, and the fixing component is used to fix the intercooler hard tube 10; a detachable guide cone 11 disposed at the front end of the intercooler hard tube 10, wherein the outer wall of the guide cone 11 is provided with a groove 111 for facilitating the installation of the hook 14, and the guide cone 11 is used to expand the rubber sheath 13;

[0025] A pull-down cylinder 2 is provided on the lower surface of the mounting plate 1, and a pull hook 14 is provided at the telescopic end of the pull-down cylinder 2. The pull hook 14 pulls the rubber sleeve 13 sleeved on the guide cone 11 downward through the pull-down cylinder 2, thereby causing the expanded rubber sleeve 13 to be sleeved on the front end of the intercooler hard tube 10.

[0026] Secondly, the fixing assembly includes a first mounting post 3 and a second mounting post 4 arranged sequentially along the axial direction of the intercooler hard tube 10, and an abutting component located at the rear end of the intercooler hard tube 10. Both the first mounting post 3 and the second mounting post 4 are provided with a clamping wrench 9. The abutting component is used to prevent the intercooler hard tube 10 from shaking back and forth.

[0027] Secondly, in this embodiment, the intercooler hard tube 10 is provided with a first mounting protrusion 101. During the rubber sheath assembly process, the first mounting protrusion 101 is nested in the limiting cavity on the first mounting post 3. The clamping wrench 9 installed on the first mounting post 3 is used to clamp the upper surface of the intercooler hard tube 10.

[0028] Secondly, in this embodiment, a second mounting protrusion 103 is provided on the rear end of the intercooler hard tube 10. During the rubber sheath assembly process, the second mounting protrusion 103 is sleeved on the second mounting post 4, and the clamping wrench 9 installed on the second mounting post 4 is used to clamp the upper surface of the intercooler hard tube 10.

[0029] Secondly, in this embodiment, the abutting component includes a limiting block 5 disposed on the mounting plate 1, a pressing block 8 slidably disposed in the limiting block 5, a third mounting post 6 disposed on the mounting plate 1, and a first cylinder 7 disposed on the third mounting post 6. The telescopic end of the first cylinder 7 is connected to the pressing block 8. The rear end of the intercooler hard tube 10 is provided with a limiting protrusion ring 102. During the rubber sheath assembly process, the first cylinder 7 pushes the pressing block 8 to slide in the limiting block 5, and cooperates with the limiting protrusion ring 102 to axially fix the rear end of the intercooler hard tube 10.

[0030] The rubber sleeve expansion assembly fixture described in this embodiment prevents misalignment of the rubber sleeve 13 during assembly by configuring a fixing component on the mounting plate 1 for fixing the intercooler hard tube 10. Specifically, it includes nesting the intercooler hard tube 10 with the first mounting post 3 and the second mounting post 4 respectively, in conjunction with the first mounting protrusion 101 and the second mounting protrusion 103 on the intercooler hard tube 10, and fixing it with the clamping wrench 9 on the first mounting post 3 and the second mounting post 4 to prevent abnormal rotation of the intercooler hard tube 10. The first cylinder 7 pushes the clamping block 8 to slide in the limiting block 5, and the limiting protrusion ring 102 axially fixes the rear end of the intercooler hard tube 10. Secondly, as Figure 4 As shown, by configuring a corresponding guide cone 11 at the front end of the intercooler hard tube 10, the rubber sleeve 13 fitted on the guide cone 11 is pulled down by the hook 14 and the pull-down cylinder 2, thereby making the rubber sleeve 13 fit on the front end of the intercooler hard tube 10. This effectively reduces the degree of manual intervention in the installation process of the rubber sleeve at the end of the intercooler hard tube, making the entire rubber sleeve installation process time-saving and labor-saving.
